Title: Analyzing integer is not a palindrome
Solution: For negative numbers or numbers ending in 0 and not to zero, it is certainly false, for the other number, use another number y after the deposit with numbers anyway, and then began to dump the anti-x y, where y> = x when the reverse stop, after all x and y and y, if x and y are equal (even numbers) or y / 10 is equal to x (odd number), then it is a palindromic
class Solution { public: bool isPalindrome(int x) { if (x < 0 || (x % 10 == 0 && x != 0)) return false; int left = x, right = 0; while (left > right){ right = right * 10 + left %10; left = left / 10; } if (left == right || left == right / 10){ return true; } else{ return false; } } };
